WILLIAM L. MORRIS, OF CHIGAGO, ILLINOIS.

HIGH-SPEED RECORDING-GAGE.

To all whom it may concern:

Be it known that I, WILLIAM L. MORRIS, a citizen of the United States,resident of Chicago, county of Cook, and State of Illinois, haveinvented a new and useful Improvement in High-Speed Recording-Gages, ofWhich'the following is a specification, the principle of the inventionbeing herein .explained and the best mode in which I have contemplatedapplying that principle, so-as to distinguish it from other inventions.

My invention relates to recording gages, and particularly to such gagesas are designed to have a plurality of cycles or turns whereby a highspeed'of revolution or reciprocation can be obtained, and, consequently,a very detailed record of the varying pressures that are measured.

Said invention consists of means hereinafter fully described andspecifically set forth in the claims.

The annexed drawings and the following description set forth in detailcertain mechanism embodying the invention, such dis' closed meansconstituting, however, but one of the various mechanical forms in whichthe principle of my invention may be ap plied.

In said annexed drawings :-Figure 1 represents a vertical longitudinalsection of a form of mechanism embodying my invention; Fig. 2 representsa horizontal section taken upon the plane represented by the line 2-2,Fig. 1; Fig. 3 represents a diagram of a chart used with the mechanismillustrated in Figs. 1 and 2; Fig. 4 represents the chart as it would bewhen rolled into position and gummed upon the drum; Fig. 5 represents aside elevation of the rock-shaft that oper ates the marker; Fig. 6represents the lower end of the drum-supporting screw and the stop-pinto prevent the drum from falling off Fig. 7 represents a verticalsection taken upon the plane indicated by the line 7-7, Fig. 8, theparts being developed into a straight line to aid in showing thedetails; and Fig. 8 shows a plan of the clock mecha nism used to operatethe revolving cylinder.

The object of my invention is to design a recording gage that can beoperated at a greater speed than those which have been heretofore inuse, and at the same time provide achart upon which the pressures can berecorded and which are readily adapted for filing away for reference.

- In my invention I obviate the difficulties Specification of LettersPatent.

heretofore connected with the use of chart supporting mechanisms oflimited area by providing means whereby charts carried by saidmechanisms are passed by the marking instrument a pluralit of times;also by providing means whereby the relative positions of said chart andsaid marking instrument are changed at each cycle so as to present a newportion of the chart to the marking instrumenteach time. The mechanismadapted to meet these requirements is not material, and may assume agreat number of forms comprising a cylindrical supporting member adaptedto revolve and simultaneously move axially, thereby bringing a newportion of the chart into the path of the marking instrument everyrevolution thus the drawings presented herewith, to which reference hasbeen made, and in which the same reference letters refer to like parts,is shown my preferred form of apparatus for securing the plurality ofcycles of movement of the supporting member for the recording chart, andthe means for presenting different portions of said chart to the markinginstrument at each cycle.

The chart supporting member is a cylindrical drum A, Figs. 1 and 2. Thisdrum is carried by a screw B, which is supported by the cross-arm C andthe posts C. The latter are received in the base or body D' by means ofthe tapped bosses D. Flanges D are provided for the body D, whereby itmay be attached to'a wall by means ofbolts in the holes D This body D isin the form of a box with the front end open and provided with a hingeddoor D with glass D in the same. below the box at the back of the same,as in dicated in dotted lines in Fig. 2. Two large circular openings areprovided in the case through which the drum may pass, and rims D arestiffening edges for these openings. A Bourdon spring for givingmovement to the marker is shown at E with a nipple E for pipe connectionof the same with-the pressure to be measured. Pivot screw E connects thespring to the marker mechanism. The marker pen is shown at F with an armF to carry the same, the latter being connected to a bell-crank F whichis carried on a pivoted shaft F. This latter shaft is supported onneedle points in the supports F which screw into the body or case D. ThescrewF is provided by means of which the marker may be withdrawn the Theflanges D are placed above and marking.

I nated at H which can be set at the elevarequired distance from thechart. A second screw F is provided for preventing the marker frombearing too heavily upon the chart. The latter thus serves virtually asa guiding screw. For the purpose of regulating the amount of markertravel to correspond with the chart lines, a clamp and screw F 7 areprovided. Connection F communicates motion to the marker from theBourdon spring E by means of the pivot F and the pivot block F Adjustingscrews F enable the raising or lowering of the working range of themarker F.

G designates a revolving marker release adapted to hold the marker offthe chart until the latter is in position or ready for the The markerrelease G is provided with a side bar G eccentric with G,

a handle G and stops G adapted to hold the release against or away fromthe marker arm F.

A second marker, whlch 1s fixed, 1s desigtion upon which it is desiredto show the line on the chart. The pen or indicator is shown at H, whichcan be moved toward not been previously provided.

the chart by slacking the nut H and sliding the marker H in the slot Hwhich lies on the radial line of the drum A. By means of this fixed penH the accuracy of ,the chart can be checked, and also with it, standardlines can be drawn, in case they have The drum-supporting screw B. whichis preferably a double-thread of about a of an inch pitch, has two nutsB and B Fig.

1, at its upper end provided with thread engagement. By means of thesenuts the drum A and screw B ,can be raised or lowered to enable thesetting of the marker pen H so that the latter will trace over a printedline. It is necessary to slack off the tap nut and revolve the drum ifthe marker pen does not stand over the correct time, when the chart isstarted.

J, Fig. 1 shows the support of the thread engaging mechanism providedwith a shaft 7' and a conical rim roller or wheel J with a fixed holderon the shaft of J at the back of the bearing at J so that the tension ofthe spring is given to the washer and support J instead of forcing thewheel J against the screw B. The small pin J 3 prevents the shaft andwheel J from falling out of their places when the drum A is handled offthe screw B. The driver sleeve is shown at K, Figs. 1, 7 and 8, and isprovided with a feather K which engages in the feather-way B on thescrew B, the feather-way having a lution of cylinder A about the sleeve,since the cylinder normally tends to move helically along the screw Bunder the force of gravity. Obviously by using a dlfferent form ofthread-engaging mechanism than the wheels J and associated parts, as forinstance an ordinary nut, the combination of sleeve and clock orequivalent motor would form a positive drive instead of merely aregulating device. Such clockworks connect with gear K and K which arecarried on the sleeve K. Gear K engages with a train of gearing to themain spring K winding key K ratchet K and intermediate gears K. The gearK connects with the timing escapement through the train of gears Kescapement K balancewheel K, and hair-spring K. The clock details are ofstandard construction, the main spring -being quit-e light, since theweight of th e drum tends to operate the clockworks. When the nut B istight, the drum A can be revolved around the screw B only as the clockworks permit the same. The cap A over the clock works, shown in Fig. 1,is dust-proof to protect the parts. Drum A is carried by the clock bymeans of the screws A Fig. 1, that screw into separate parts of. thesame.

In connection with the lower end of the drum A there is provided a ringA Fig. 1, adapted to fit over and be frictionally secured to such endwhen the chart A has been rolled about. the drum and its edges gummedtogether in the manner above described. Such ring it will accordingly beseen will serve to support the chart, retaining it in whatever angularposition upon the drum it may have been placed.

The chart A, Fig, 3, is rolled around the drum, as shown in Fig. 4, withthe lines L and I) coinciding when laid upon the drum. To remove thechart, a knife is passed along the crease at L" leaving the narrowgummed strip remaining at the left side of the sheet along the line L.The holes L are provided for the purpose of filing. The lines L passalong the point of the indicator H, shown in Fig. 1, and can be eitherprinted on the chart or plotted with the fixed pen H.

These lines are standard lines and represent a known pressure or amount.If the pres sure is to be changed, the screws F and F can be adjusted asis necessary, using a standard test gage. The smaller subdividing linesL give the amount of variation from the standard lines L it having beennoted on the chart what this may be, and the amount of pressurevariation from line L .to line L also noted on the regular pressuregage. The lines L are noted with the hours that each line starts on theleft hand side designated by number L and by the numbers L on the otherend of the line showing the time at which the marker pen F ran off theline. The lines L show the number of minutes past the hour at which themarker pen F passed along the lines L or L The marker pen F starts atline L on lower line L or L at either 12 oclock noon or night, and placefor noting this starting period is provided on the chart, as shown. Whenthe chart is completed at the end of the twenty-four hours, the markerpen will be at the upper line L or close vicinity and on the line L nearthe upper figure 12.

The chart, drum and clock works are removable from the case D and thescrew B by giving the drum a slight turn with the hand, carrying thewheels J over the stoppin 13*, Fig. (5. The feather K disengages fromthe screw B ust previous to the time at which the wheel J comes intocontact with the pin B thereby leaving K free to revolve out ofengagement with screw B, and allowing the drum to be suspended on thescrew B until the attendant takes the drum out and replaces the chartwith a new one. In replacing the drum ready to startv the chart, it islifted up to the end of the screw, revolved until the feather K meetsits feather-way B and raised up to its full height, the wheelsJrecoiling back against their springs, as they are pressed back by eachtooth of the screw B. The tension on these springs is quite light, asthewheels would stay to tooth without the same.

The operation of my improved recording gage is as follows: A chart ismoistened at the gummed edge, placed over the drum and secured to thesame. The drum is then raised up to its place; the screw B is slackedofi' and the drum, together with the screw, is-revolved around to itsproper time, this being the same as the regular clock would show, hourand minute. After setting the time, note is taken to ascertain if theset lines L correspond with the indicator II, and, if it does not, theproper adjustment is secured by means of the two nuts B and B The nuts Band B are then locked. The retractor arm G is then turned around toallow the pen F tocome into contact with the chart, and the same is madeto bear properly upon the chart. The marker is caused to rise above thestandard, set line L by the Bourdon spring E or to fall below said line,according as the spring is straightened out more or less by a greater orless pressure than the pressure necessary to secure a standard line LThe amount that the marker indicates above or below the standard lines Lis a known quantity and stated on the chart. The chart and drum arecaused to rotate, and, in order to expose new portions of the chart foreach time the marker travels over the chart, the drum and chart drop onthe screw an amount equal to the drop of lines L also equal to thevertical distance between two adjacent lines L The end of one of thelines L is, on the drum, the beginning of the next one, thus providingone continuous thread when exposed on the drum. When the chart has runits full amount, it ceases to revolve further, and the marker F-retraces its path as given by the spring tube E. Many variations of myinvention may be provided without departing from the same, the spirit ofwhich is to provide mechanism that shall pass the chart by the marker aplurality of times, and change the plane of travel each time, so as tosuccessively expose new or untraveled portions of the chart.

- Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed provided the means stated by'any one ofthe followingclaims or the equivalent of such stated means be employed.
